STMicroelectronics STM32U073KCU6TR, 32 bit ARM Cortex M0+, STM32 Microcontroller, 56 MHz, 256kB FLASH, 32-Pin UFQFPN

The STMicroelectronics devices are ultra-low-power microcontrollers based on the high-performance Arm Cortex-M0+ 32-bit RISC core operating at a frequency of up to 56 MHz The devices embed high-speed memories (up to 256-Kbyte flash memory and 40-Kbyte SRAM with hardware parity check), and an extensive range of enhanced I/Os and peripherals connected to APB and AHB buses, and a 32-bit multi-AHB bus matrix. They also embed protection mechanisms for embedded flash memory and SRAM, such as readout protection and write protection. The devices offer a 12-bit ADC, a 12-bit DAC, two embedded rail-to-rail analog comparators, one operational amplifier, a low-power RTC, one general-purpose 32-bit timer, one 16-bit PWM timer dedicated to motor control, three general-purpose 16-bit timers, and three 16-bit low-power timers.
